I'm going to make 2 comments about this,
1. There is the door, don't feel that you need to stick around if there is so little available.
2. The best secrets are never discussed out in open forums, they are discussed at the drinks / dinners which are organised by forum members. If you want the real gold (should I say platinum?) come to the drinks / dinners / social meetups.
Red Roo leaving is a bit of a pity, but I guess it's the whole limited resources thing. AFF certainly has a lot of high value pax, but one could also argue that those same people are also on facebook / twitter / the next big social media. It takes time and resources for QF to have an active member here, and since most of us will continue flying QF (or not flying QF as the case may be) regardless of a dedicated company rep, having a rep here would not be increasing the bottom line, like it would through other social media outlets.
It's a shame, Red Roo has always looked after me quite well, the few issues I have had they sorted out very quickly to my satisfaction (or at least my expectation). The flip side is of course it doesn't remove this forums usefulness by any stretch of the imagination. There will continue to be new things to learn, discussions about travel and all those little nuggets of info which mean I typically have a much better flying experience than all of my (non-AFF) friends.
